Hi @Faisal,
The thread Demultiplex pair end sequence import problem may be of help to you.
Basically, this import type expects the naming of the files to be in this order:
sample identifier, the barcode sequence or a barcode identifier, the lane number, the read number, and the set number
In your case, it looks like S100 etc. is the sample identifier, so you could delete W28_J0545_ from the name, but then the string is still missing a barcode identifier.
You could use the general manifest format to import. The manifest file that gets inputted into this is what @Mehrbod_Estaki is referring to.
